Operator for controlling electrically adjustable furniture

Abstract

An operator for controlling electrically adjustable furniture includes a housing and an actuation panel movably supported in the housing to form a cover body. A circuit board is provided in the housing, and a main control unit for detecting an actuation signal is provided on the circuit board. A first switch for generating a first actuation signal and a second switch for generating a second actuation signal are provided between the actuation panel and the main control unit, and a third switch for generating a third actuation signal is provided between a bottom wall of the housing and the main control unit. The main control unit issues a first command when simultaneously detecting the first actuation signal and the second actuation signal, and the main control unit issues a second command when simultaneously detecting the first actuation signal, the second actuation signal, and the third actuation signal.

What is claimed is:

       4. The operator for controlling electrically adjustable furniture according to  claim 1 , wherein the second switch is a first electromechanical switch provided on the main control unit, and the actuation panel motions relative to the housing to actuate the second switch. 
     
     
       5. The operator for controlling electrically adjustable furniture according to  claim 4 , wherein the first switch and the second switch are aligned in a vertical line perpendicular to the actuation panel, such that the first switch is simultaneously actuated when the second switch is actuated. 
     
     
       6. The operator for controlling electrically adjustable furniture according to  claim 5 , wherein a rotating shaft parallel to a surface of the actuation panel is provided at each of two ends of the actuation panel, and a rotating shaft mounting groove for mounting the rotating shaft is provided at an upper end opening of the housing, the actuation panel rotates in the housing via the rotating shafts, and a connecting line between the rotating shafts at the two ends serves as a rotating centerline for the actuation panel. 
     
     
       7. The operator for controlling electrically adjustable furniture according to  claim 6 , wherein an actuation projection is provided at a bottom of the actuation panel, such that when the actuation panel rotates, the second switch is actuated via the actuation projection. 
     
     
       8. The operator for controlling electrically adjustable furniture according to  claim 4 , wherein a rotating shaft parallel to a surface of the actuation panel is provided at each of two ends of the actuation panel, and a rotating shaft mounting groove for mounting the rotating shaft is provided at an upper end opening of the housing, the actuation panel rotates in the housing via the rotating shafts, and a connecting line between the rotating shafts at the two ends serves as a rotating centerline for the actuation panel. 
     
     
       9. The operator for controlling electrically adjustable furniture according to  claim 8 , wherein an actuation projection is provided at a bottom of the actuation panel, such that when the actuation panel rotates, the second switch is actuated via the actuation projection. 
     
     
       10. The operator for controlling electrically adjustable furniture according to  claim 1 , wherein the third switch is a second capacitive sensing touch switch, a second touch sensing zone is provided on an inner sidewall of the bottom wall of the housing, and the second capacitive sensing touch switch comprises a second capacitive touch sensing element disposed in the second touch sensing zone; or the third switch is a pushbutton switch, and a button of the pushbutton switch is disposed on the bottom wall of the housing. 
     
     
       11. The operator for controlling electrically adjustable furniture according to  claim 1 , wherein a display is provided on the operator; the display is disposed on the actuation panel; or, the display is disposed on the housing; or the display is arranged side-by-side with the actuation panel. 
     
     
       12. The operator for controlling electrically adjustable furniture according to  claim 1 , wherein the actuation panel comprises a first actuation panel and a second actuation panel; wherein the first switch is a second electromechanical switch disposed on the main control unit, the second switch is a third electromechanical switch disposed on the main control unit, and the first actuation panel motions to actuate the second electromechanical switch, and the second actuation panel motions to actuate the third electromechanical switch.
